BACKGROUND

The present invention generally relates to cognitive devices and, more particularly, to a cognitive and interactive sensor based smart home solution.

A cognitive device (sometimes called a smart speaker) is a hardware device that facilitates user interaction with a virtual assistant (also called a smart assistant or an intelligent personal assistant). Such devices continuously listen for a wake word to be spoken by a user and perform various tasks based on voice commands from the user. For example, such devices are capable of voice controlled music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic and other real time information. Such devices can also control smart devices as a home automation hub in a smart home environment.

Conventional devices do not differentiate between plural different users, and typically require the use of a power cord to plug into a power supply. For example, some devices purport to be smart devices, but in actuality are not interactive and merely take commands from a mobile app. Some smart home assistants have the ability to interact with a person, but they are limited to a single user account and aren't convenient to install in plural rooms. Some smart home devices operate on protocols to connect to an app, but their voice interaction is only possible through a separate user device.

DETAILED DESCRIPTION

The present invention generally relates to cognitive devices and, more particularly, to a cognitive and interactive sensor based smart home solution. In accordance with aspects of the invention, there is a Smart Home Sensor Solution that uses power outlets, connects peer to peer to detect precise context of the user, and connects to cognitive APIs hosted in the cloud to provide intelligent interaction. In embodiments, a smart sensor is configured to receive a voice input from a user, identify the user based on smart speech recognition, and perform a function in response to the voice input and based in part on user data associated with the identified user. In embodiments, the smart sensor is configured to identify the user from plural registered users. In this manner, each user's interaction with the system is personalized based on their own data. Using smart speech recognition to identify a user and then leveraging the user's own data in performing a function provides a technical contribution over systems that are limited to interacting with only a single user.

In embodiments, the smart sensor plugs directly into a standard electrical outlet without a power cord. The smart sensor may be on a local network with other smart appliances such as televisions, thermostats, lighting systems, security systems, sprinkler/irrigation systems, health/medical monitoring devices, etc. The smart sensor may include programming (e.g., APIs) that permit the smart sensor to interface with (e.g., send data to and receive data from) the smart appliances. In this manner, a user may control the smart appliances via interaction (e.g., voice input) with the smart sensor. For example, a user may provide a voice command to the smart sensor to turn on the television, and the sensor may receive the input and send data through the network that causes the television to turn on. User devices, e.g., smartphones, tablets, laptops, desktops, etc., can connect to the local network. In this manner, a software app on a user device may be used to configure the smart sensor, register different users with the smart sensor, and expose user data stored on the user devices for use by the smart sensor.

In aspects, the smart sensor may include a cognitive computing component and/or may communicate with a cloud based cognitive computing system. In this manner, a function performed by the smart sensor, e.g., in response to a user input, may be based in part on cognitive analysis of the user input and/or the user data. In this manner, aspects of the invention provide a technical contribution of using cognitive analysis in an interactive sensor based smart home solution.

In embodiments, plural smart sensors may be arranged in a system such as a mesh network. Each respective smart sensor of the system may be plugged into a different outlet, e.g., in different rooms of a building such as a home, office, hospital, etc. In this manner, plural users may interact simultaneously with different smart sensors in the system to obtain personalized functionality. Connecting plural smart sensors that can operate independently with different users provides a technical solution to the technical problem of other devices that are limited to interacting with one user at a time.

In accordance with aspects of the invention, a system includes plural smart sensors connected in a mesh network and communicating with a cognitive computing system in a remote network such as the cloud. In embodiments, the system utilizes cognitive APIs, such as smart speech, that permit the system to recognize who is talking and use their device for base information including but not limited to contact list, music, etc. In embodiments, the system is configured to permit a user to control aspects such as volume, speed of the response language, vocabulary (e.g., depending on parameters such as age, who is interacting with the system, etc.), speech to text, text to speech, context awareness, and device management. Software in the system (e.g., stored and executed on each smart sensor) may be configured to provide one or more of voice control, peer interaction, and cloud interaction. Each smart sensor may include an embedded operating system (OS) that can be updated to add new options and/or features.

Each smart sensor of the system may include a microphone and speaker that are used to facilitate voice input and audio output, and that can additionally be configured as a monitoring system such as a baby monitor, hospital patient monitor, pet monitor, etc. Additionally or alternatively, each smart sensor of the system may be configured to communicate with wireless medical equipment, such as a heart rate monitor or patient locator, and to provide reporting data to an app at a user device, e.g., through the cloud.

Each smart sensor of the system may be configured to provide natural language question and answering. For example, the system may be on a local network that can communicate with an external network, e.g., the Internet, such that a smart sensor in the system can communicate with the cloud based cognitive computing system. In this manner, the system may provide natural language question and answering functionality based on the cloud based cognitive computing system. In embodiments, the natural language question and answering functionality may be personalized to a particular user. For example, a first user may have a subscription to a first tier of services with a natural language question and answering system, and a second user may have a subscription to a second tier of services with a natural language question and answering system. In embodiments, the smart sensor determines an identity of a user asking a question, communicates the question and the identity to the cloud based cognitive computing system. The cloud based cognitive computing system determines the user's subscription tier based on the received identity, accesses the cloud based cognitive system based on the user's subscription tier, determines an answer, and communicates the answer back to the smart sensor, which outputs the answer to the user via the speaker.

Each smart sensor of the system may be configured to detect the precise location of the user based on data obtained by at least one of a Passive Infrared Sensor/Repeater, a LiDAR sensor, and an Ultrasonic Sensor. In embodiments, the Passive Infrared Repeater/Sensor can detect motion, etc., and also send an infrared (IR) signal to a television or other device. For example, a smart sensor in the system may receive the voice command “turn on TV” spoken by a user within the vicinity of the smart sensor. Based on receiving this voice command form the user, the smart sensor may identify the user based on voice recognition, determine a television closest to the user (e.g., based on stored data defining a location of the smart sensor and locations of plural televisions in the home), determine the user's preferred program at this day and time (e.g., based on cognitive analysis of user data, such as historical viewing habits), and send a signal to the identified television to turn on and tune to the channel having the determined program. The smart sensor may send the signal to the television using the Passive Infrared Repeater.

In an exemplary usage, a group of smart sensors in the system can be configured to simultaneously play the same music through their respective speakers for whole house sound. In another exemplary usage, at least one first smart sensor may play first music while at least one second smart sensor plays second music different than the first music. For example, a first user located in a first room of a house may speak the command “play music.” A first smart sensor located in the first room receives the command from the first user, identifies the first user via voice recognition, accesses the first user's music library (e.g., on a user device of the first user), and plays music from the first user's music library via the speaker of the first smart sensor. In this same example, while the first music is playing on the first smart sensor, a second user located in a second room of the house may speak the command “play music.” A second smart sensor located in the second room receives the command from the second user, identifies the second user via voice recognition, accesses the second user's music library (e.g., on a user device of the second user), and plays music from the second user's music library via the speaker of the second smart sensor. In this manner, different smart sensors connected in a same system may be configured to simultaneously play different music for different users based on receiving voice commands from the different users.

Aspects of the invention are described herein as accessing and leveraging user data, e.g., data owned by one or more users registered with a smart sensor of the present invention. To the extent that implementations of the invention collect, store, or employ personal information provided by individuals (e.g., user data), it should be understood that such information shall be used in accordance with all applicable laws concerning protection of personal information. Additionally, the collection, storage, and use of such information may be subject to consent of the individual to such activity, for example, through “opt-in” or “opt-out” processes as may be appropriate for the situation and type of information. Storage and use of personal information may be in an appropriately secure manner reflective of the type of information, for example, through various encryption and anonymization techniques for particularly sensitive information.

Aspects of the invention are described herein as using one or more smart sensors for audio monitoring and/or video monitoring of physical spaces that may be occupied by one or more individuals. For example, implementations of the invention may be used as at least one of: a baby monitor, a health care monitor, a pet monitor, and a home security system. To the extent that implementations of the invention perform such monitoring, it should be understood that such monitoring shall be performed in accordance with all applicable laws concerning protection of personal information and privacy of individuals.

By plugging directly into the outlet 52, implementations of the invention avoid the disadvantages of an electrical power cord, such as unsightliness, tangles, and tripping hazard.

The at least one microphone 14 may be any number and arrangement of conventional and/or later developed devices that are configured to convert sound into an electrical signal. In embodiments, the at least one microphone 14 is configured to receive voice (e.g., spoken) input from a human user and to convert the voice input to electrical signals that are used by other components of the smart sensor 10.

In this manner, the camera 28 is configured to capture video from a large portion of the room in which the smart sensor 10 is installed.

Still referring to FIGS. 2 and 3 , the control switch 30 is a switch that a user can manipulate to selectively turn the smart sensor 10 ON and OFF (e.g., to selectively open and close a circuit that provides operating voltage to the system). The control switch 30 may include any conventional and/or later developed type of switch including but not limited to a toggle or dolly, a rocker, and a push-button switch.

In embodiments, the sync button 32 is a button that is configured to cause the smart sensor 10 to enter a sync mode which is used to setup the sensor with a network and/or a user device. For example, the sync button 32 may be a Wi-Fi Protected Setup (WPS) button or similar type of button that is usable to add (or sync) the smart sensor 10 with an existing network.

In embodiments, the USB port 34 is a Universal Serial Bus port for charging and/or data transfer. For example, a user may recharge a battery in their user device (e.g., smartphone) by connecting their user device to the smart sensor 10 via a cable that plugs into both the user device and the USB port 34. The USB port 34 may also be used to transfer data between the smart sensor 10 and a connected computing device, e.g., using a similar corded connection between the devices.

FIG. 4 shows an exemplary environment comprising plural smart sensors 10 a-n arranged in a system in accordance with aspects of the invention. The system may be deployed in a building 100 such as a house, apartment, office, hospital, etc. In embodiments, each one of the smart sensors 10 a-n is plugged into an outlet in a respective room 102 a-n of the building 100, e.g., using the power adapter 22 as described herein. The building 100 includes a gateway 104 that connects to an external network 106 (e.g., the Internet) and that provides a wireless local area network (LAN) generally depicted at 108. For example, the gateway 104 may comprise a router that provides wireless communication for the local network 108 in the rooms 102 a-n of the building 100. Any number of smart appliances A1, A2, A3, . . . , Am may be connected to the local network 108. The appliances A1-m may include, without limitation, a television, thermostat, lighting system, security system, medical devices (e.g., monitors), etc.

According to aspects of the invention, the plural smart sensors 10 a-n form a mesh network 115 that is part of or connected to the local network 108 provided by the gateway 104. In this manner, the smart sensors 10 a-n may communicate with one another, and can also communicate with the appliances A1-m. In embodiments, the smart sensors 10 a-n can interact with (e.g., issue commands to) one or more of the appliances A1-m via application program interfaces (APIs). In this manner, as described herein, the system is configured such that a user can control one or more of the appliances A1-m by issuing a voice command to one of the smart sensors 10 a-n.

Still referring to FIG. 4 , in embodiments, the system is configured to provide personalized interaction with plural different users (userA, userB, userC) each having their own user device 110 a, 110 b, 110 c. Each user device 110 a-c can comprise for example, and without limitation, any of a smartphone, tablet computer, laptop computer, wearable computer that can communicate with at least one of the smart sensors 10 a-n via the network 108.

User device 110 a, which may be representative of any of the user devices, is shown as having a processor 112, memory 120, and app 122, although it is understood that user device 110 a may have additional components (e.g., input/output device(s), network interface, battery, etc.) The app 122 is an application program or other program module that provides an interface between the user device 110 a and one or more of the smart sensors 10 a-n. In accordance with aspects of the invention, the app 122 is configured to: permit a user (e.g., userA) to register the user device 110 a with the system of smart sensors 10 a-n; permit the registered user to control certain functionality of one or more of the smart sensors 10 a-n; and expose certain user data stored on the user device 110 a to one or more of the smart sensors 10 a-n.

In embodiments, each user registers their user device with the system prior to using the system. Registration may be performed through the app 122 and may include: the user (e.g., userA) inputting credentials (e.g., username, password, etc.) via an interface of the app 122 to confirm that the user is a valid user and that the device is a valid device; and the user speaking into a microphone of the user device 110 a to provide samples of their voice that are used to set up smart speech recognition as described herein.

In accordance with aspects of the invention, the system uses smart speech recognition to determine the identity of a person speaking a voice command that is received at one of the smart sensors. The smart speech recognition may be performed locally at the smart sensor, or remotely at a cloud-based server, or some combination of both. In the local implementation, the smart sensor receives audio data (e.g., the voice command) and the voice control module (e.g., module 40 of FIG. 1 ) determines the identity of the user. In the cloud server implementation, the smart sensor receives audio data (e.g., the voice command) and transmits the audio data via the local network to the cloud-based server, which performs the processing to determine the identity of the person speaking a voice command and returns the identity to the smart sensor. In both implementations, the system compares the received audio data (e.g., the voice command) to stored data associated with each registered user (e.g., voice samples provided during registration), and uses voice recognition techniques to determine which of the registered users provided the received audio data (e.g., the voice command). In this manner, the system determines which one user of a plurality of registered users uttered the voice command that was received at one of the smart sensors.

Any number of users and user devices may be used with the system. For example, in one implementation only a single user is registered with the system and interacts with the system at any given time. In another example, plural users are registered with the system and two or more of the registered users can simultaneously interact with the system. Moreover, although plural smart sensors 10 a-n are shown in FIG. 4 , implementations of the invention are not limited to using plural sensors. Instead, a single smart sensor may be used by single or plural registered users. For example, only one user might register their user device with one smart sensor, and this user may interact with the one smart sensor to perform functions described herein (e.g., make calls using the user's contacts, play music using the user's music library, control appliances, ask questions and receive answers, etc.). As another example, plural users might share a single smart sensor, e.g., by all registering their devices with the smart sensor and taking turns interacting with the smart sensor to perform functions described herein.

In the exemplary environment shown in FIG. 4 , users userA, userB, userC have each registered their respective user devices 110 a, 110 b, 110 c with the system of smart sensors 10 a-n, and each of the user devices 110 a-c is connected to the local network 108. Plural exemplary use cases will be described with reference to FIG. 4 to illustrate functionality of the system.

A first exemplary use case illustrates how the system may be configured to provide telephone call functionality that is personalized based on a user interacting with one of the smart sensors. In embodiments, the system may be configured to receive a voice command to make a telephone call, determine which user of the plural registered users uttered the voice command, access a contact list of the determined user to initiate the requested call, and conduct the call via one of the smart sensors. In this first use case, userA is in room 102 a and speaks a voice command “call Dave.” Smart sensor 10 a receives the voice command via its microphone 14, and the voice control module 40 of smart sensor 10 a uses smart speech recognition to determine that the voice command was uttered by userA. Based on determining the user is userA, the smart sensor 10 a accesses userA's contact list on userA's registered device (e.g., user device 110 a), finds Dave in userA's contact list, and initiates a telephone call to the telephone number for Dave from userA's contact list. The smart sensor 10 a is configured to communicate with the user device 110 a (via the local network 108) to cause the user device 110 a to make the telephone call while playing the audio of the telephone call through the smart sensor 10 a. For example, during the call, userA's voice is received at the microphone 14 of the smart sensor 10 a and transmitted to the user device 110 a, which transmits the voice data to Dave's end point. Conversely, Dave's voice data is received at the user device 110 a, which transmits Dave's voice data to the smart sensor 10 a, which plays Dave's voice data via its speaker 16.

In this first exemplary use case, userA need not be in the same room with the user device 110 a during the telephone call. For example, userA may be in a first room (e.g., room 102 a) and the user device 110 a may be in a different room (e.g., room 102 n). In embodiments, the smart sensor 10 a communicates with the user device 110 a via the local network 108, which advantageous provides a user the ability to control functions of their user device (e.g., conduct telephone calls, play music, etc.) via voice interaction with one of the smart sensors 10 a-n in any room.

Still referring to the first exemplary use case, the system may be configured to simultaneously handle plural telephone calls for plural different users. For example, while userA is conducting a call with Dave by interacting with smart sensor 10 a in room 102 a, userC who is in room 102 c with smart sensor 10 c may speak a command “call Ethel.” In this case, the smart sensor 10 c receives the voice command via its microphone 14, and the voice control module 40 of smart sensor 10 c uses smart speech recognition to determine that the voice command was uttered by userC. Based on determining the speaker is userC, the smart sensor 10 c accesses userC's contact list on userC's registered device (e.g., user device 110 c), finds Ethel in userC's contact list, and initiates a telephone call to the telephone number for Ethel from userC's contact list. In this manner, a first user (e.g., userA) may interact with a first smart sensor (e.g., smart sensor 10 a) simultaneously while a second user (e.g., userC) interacts with a second smart sensor (e.g., smart sensor 10 c), and the system can simultaneously provide personalized interactions for both users.

A second exemplary use case illustrates how the system may be configured to provide ‘following’ functionality to a user that is moving throughout a physical space in which plural smart sensors are installed. In embodiments, the system may be configured to receive a voice command to play music, determine a first smart sensor that is closest to the user, play the requested music via the first smart sensor, detect that the user moves to a location that is closer to a second smart sensor, and discontinue playing the music via the first smart sensor and begin playing the music via the second smart sensor based on the detecting.

In this second use case, userB is in room 102 b and utters the voice command “play music.” userB may be sufficiently close to plural ones of the smart sensors such that more than one of the smart sensors detects the received voice command via their respective microphones 14. For example, userB's voice command may be detected by each of smart sensors 10 a, 10 b, and 10 n. In embodiments, based on receiving a voice command, the system is configured to determine which of the plural smart sensors in the system is closest to the user that uttered the command. According to aspects of the invention, each of the smart sensors that receive a command (e.g., smart sensors 10 a, 10 b, and 10 n in this example) uses data from its respective sensors 26 to determine a distance to a user. For example, each of the smart sensors 10 a, 10 b, and 10 n may use one or more of PIR sensor data, LiDAR sensor data, and ultrasonic sensor data to determine a physical distance from the respective smart sensor to the user. The smart sensors 10 a, 10 b, and 10 n may utilize their peer interaction module 42 to communicate with each other (e.g., via the local network 108) to compare results to determine which of the smart sensors 10 a, 10 b, and 10 n is closest to the user. In this example, the smart sensors 10 a, 10 b, and 10 n determine that smart sensor 10 b is closest to userB when userB utters the voice command “play music.” Based on this determination, the smart sensor 10 b plays music to satisfy the request. For example, based on identifying userB via smart speech recognition, the smart sensor 10 b may access userB's registered device (e.g., user device 110 b) and play music from the user device 110 b via the speaker 16 of the smart sensor 10 b.

Still referring to the second exemplary use case, userB may move (e.g., walk) from room 102 b to room 102 n (as depicted by arrow “B”) while the music is playing via the speaker 16 of the smart sensor 10 b. In embodiments, the system may be configured to detect that a user has moved from a first location to a second location and cause the music to follow the person to the second location. For example, the smart sensor 10 b playing the music may use data from its sensors 26 (e.g., PIR, LiDAR, and/or ultrasonic) to determine that userB is moving away from the smart sensor 10 b, and the smart sensor 10 n may use data from its sensors 26 (e.g., PIR, LiDAR, and/or ultrasonic) to determine that userB is moving toward the smart sensor 10 n. The smart sensors 10 b and 10 n may use their peer interaction modules 42 communicating via network 108 to compare the determined location of userB, and to determine when userB has moved closer to smart sensor 10 n. In embodiments, based on determining that the userB has moved to a location that is closer to smart sensor 10 n than to smart sensor 10 b, the smart sensor 10 b stops playing the music and the smart sensor 10 n begins playing the same music via its speaker 16. The system can be configured to fade the music out of the first smart sensor (e.g., smart sensor 10 b) and fade the music into the second smart sensor (e.g., smart sensor 10 n).

The second exemplary use case is described with respect to playing music, but aspects of the invention may provide ‘following’ for other functions such as television, lights, thermostat, etc. For example, appliance A1 may be a first television and appliance A2 may be a second television. userB may utter a voice command to smart sensor 10 b that causes smart sensor 10 b to control appliance A1 (the first television) to play a particular show. For example, based on receiving the voice command, the smart sensor 10 b may use one of the APIs 46 to issue a command to the appliance A1 (the first television) to play the requested show. Then, in a manner similar to that described with respect to the music ‘following’ use case, the system may be configured to stop playing the show on appliance A1 (the first television) and to begin playing the same show on appliance A2 (the second television) based on userB moving out of room 102 b and into room 102 n.

Still referring to FIG. 4 , the system can be configured to use cognitive analysis in generating a response (e.g., an output) based on a user input. The cognitive analysis may be performed by a cognitive module 48 at the smart sensor, by a cloud-based cognitive computing system 130, or a combination of both. The cognitive analysis may comprise a tone analysis of the voice command to determine a tone of the user, and the output generated by the system in response to the voice command may be based at least in part on the determined tone of the user. For example, userA may utter the voice command “play music” and this voice command may be detected by the microphone 14 of smart sensor 10 a. In this example, the system uses cognitive analysis, specifically tone analysis, to determine the tone of the uttered voice command as happy. Based on this determined tone, and based on identifying userA via smart speech recognition, the smart sensor 10 a accesses userA's music library on the user device 110 a and selects music that matches the determined tone. Specifically, in this example, the smart sensor 10 a selects happy music from userA's music library on user device 110 a based on the determined happy tone of the voice command, and plays the selected music via the speaker 16. In this manner, the output of the smart sensor 10 a is not only personalized based on the user data (the user's own music library), but it is also cognitively personalized based on cognitive analysis of the command spoken by the user.

With continued reference to FIG. 4 , the system may use cognitive analysis to control how the system outputs an audio response, e.g., a response to a user question. For example, userA may utter the question “what is the weather,” which is detected by the microphone 14 of smart sensor 10 a. In this example, the system uses cognitive analysis to determine at least one of speech rate (e.g., slow, medium, or fast) and speech volume (e.g., quiet, normal, or loud) of the detected question. Based on the cognitive analysis, when outputting an answer via its speaker 16, the smart sensor 10 a may adjust the speech rate and/or speech volume of the outputted answer to match that determined for the question.

In accordance with aspects of the invention, the system may use cognitive analysis to determine user preferences from past interactions. For example, the system may store data regarding the television shows that a user has watched in the past. For example, userA might speak the voice command “turn on the television” and this command may be received via the microphone 14 of smart sensor 10 a. Based on receiving this voice command, the system may determine using smart speech recognition that userA spoke the command and then analyze the user data associated with userA to determine userA's preferred show that corresponds to the current day (of the week) and time of the voice command. Upon making the determination, the smart sensor 10 a may issue a command (e.g., via API 46) to the television that is determined as closest to userA to turn on and tune to the determined show. The data defining user preferences may be stored at any suitable device or combination of devices with in the environment.

In embodiments, when the cognitive analysis is performed by the cloud-based cognitive computing system 130, the smart sensor (e.g., smart sensor 10 a) may utilize the cloud interaction module 44 (shown in FIG. 1 ) to send data to and receive data from the cloud-based cognitive computing system 130.

According to aspects of the invention, the system may be configured to provide natural language question and answering. For example, userA may speak a voice command in the form of a question that is received by the microphone 14 of smart sensor 10 a. Based on receiving the question, the cloud interaction module 44 (shown in FIG. 1 ) may send data (e.g., data defining the question) to the cloud-based cognitive computing system 130, which uses conventional and/or later developed techniques to determine answer the question. In this example, the smart sensor 10 a receives data from the cloud-based cognitive computing system 130 (e.g., data defining the determined answer) and plays (outputs) the answer to the question via its speaker 16.

In embodiments, the natural language question and answering may be personalized to the user that asks the question. For example, in the preceding example, the smart sensor 10 a may use smart speech recognition to determine that userA is the user the asked the question that was received at the microphone 14. In embodiments, the data that the smart sensor 10 a sends to the cloud-based cognitive computing system 130 may include credentials or other identifying information associated with userA. The cloud-based cognitive computing system 130 may use the credentials or other identifying information to tailor the answer that it determines in response to the question. For example, userA may be a doctor who has a professional medical subscription with the cloud-based cognitive computing system 130, the professional medical subscription being different (e.g., having different data and/or analytics) than a basic subscription with the cloud-based cognitive computing system 130. In embodiments, the cloud-based cognitive computing system 130 uses data and/or analytics associated with the professional medical subscription in determining an answer to the question that was received at the smart sensor 10 a, and returns the answer to the smart sensor 10 a for outputting to userA.

With continued reference to FIG. 4 , in embodiments each user may use the app 122 to set user preferences, and the system may generate an output (e.g., perform a function) based at least in part on the user preferences. In embodiments, a smart sensor may be configured to: use smart speech recognition to determine a user that provides a voice input, access user preferences stored on the user device associated with the determined user, and format an output based on the user preferences.

A first exemplary user preference is a voice that is used by the smart sensors 10 a-n when providing a response to a user. For example, each user may use the app 122 to select a voice from a list of predefined voices. Then, when a user interacts with one of the smart sensors, the smart sensor provides its spoken output using the voice selected by the user in the user preferences.

A second exemplary user preference is a vocabulary that is used by the smart sensors 10 a-n when providing a response to a user. For example, each user may use the app 122 to select a vocabulary set from a list of plural predefined vocabulary sets. Then, when a user interacts with one of the smart sensors, the smart sensor provides its spoken output using the vocabulary set selected by the user in the user preferences.

A third exemplary user preference may be parental controls for sensitive content. For example, a parent may permit a minor to become registered user with the system so that the minor may enjoy the benefits of interacting with the system. However, the parent may wish to have the option of controlling content that the system presents to the minor. In embodiments, the app 122 permits a user to set user preferences that control types of content that is presented via the system. For example, the app 122 may permit a user to set a user preference regarding music, i.e., that music identified as containing explicit language will not be played by the system, whereas music identified as not containing explicit language can be played by the system. As another example, the app 122 may permit a user to set a user preference regarding search results content, i.e., the system will filter search results and/or answer based on explicit content when the system determines (using smart speech recognition) that a minor provided the voice command that generated the search results and/or answer. As another example, the app 122 may permit a user to set a user preference regarding television content, i.e., the system will not instruct a television to play an R-rated show or movie when the system determines (using smart speech recognition) that a minor provided the voice command to play the R-rated show or movie.

FIG. 5 shows a block diagram of a system in accordance with aspects of the invention. The system shown in FIG. 5 may be similar to that of FIG. 4 in that is includes plural smart sensors 10 a-n installed in rooms 102 a-n of a building 100 in which a gateway 104 provides a local network 108. The implementation shown in FIG. 5 illustrates how a user may access data from the plural smart sensors when the user and their user device are remote from (e.g., external to) the local network.

As shown in FIG. 5 , userA and user device 110 a are at a location that is outside the local network 108, and in which the user device 110 a is connected to the external network 106. In embodiments, the app on the user device 110 a (e.g., app 122) is configured to access the one or more of the smart sensors 10 a-n to provide data from the one or more of the smart sensors 10 a-n while the user device 110 a is not directly connected to the local network 108.

In the example shown in FIG. 5 , the user device 110 a may access data from the camera 28 of sensor 10 a and from the camera 28 of sensor 10 b, and may display the video data from these cameras on the display 200 of the user device 110 a. In embodiments, each smart sensor 10 a-n is configured to detect motion using sensors 26 and to communicate to the app 122 that motion has been detected. The app 122 may be configured to display an indication of each smart sensor that indicates motion detection, and to permit the user to select one of the indicated smart sensors to view video data captured by the camera of the selected one of the smart sensors. For example, in FIG. 5 the app 122 receives data from smart sensors 10 a and 10 b that each of these sensors detects motion. Based on this, the app 122 causes the user device 110 a to display an indication 202 that smart sensors 10 a and 10 b each detect motion. The user may provide input to the user device 110 a to select one of the indicated smart sensors (e.g., smart sensor 10 b), at which point the app 122 obtains video data from the camera of the selected smart sensor 10 b and causes the user device 110 a to display the video data 204 on the display 200. In this manner, implementations of the invention may provide a video monitoring system, such as a pet monitor that a user can employ to check in their pet(s) while the user is away from their home.

Still referring to FIG. 5 , based on detecting subsequent movement at an additional smart sensor, e.g., at smart sensor 10 n when the object moves as shown by arrow “M”, the app 122 may be configured to generate an update or alert at the user device 110 a. In one example, the app 122 causes the user device 110 a to return to a screen that displays an indication 202 of all smart sensors currently detecting motion, and wait for the user to select one of the indicated smart sensors. In another example, the app 122 automatically causes the user device to display video data from smart sensor 10 n, e.g., in a ‘following’ as described herein. In this manner, implementations of the invention may provide a video monitoring system with following functionality.

Although FIG. 5 is described with respect to video monitoring, it is to be understood that aspects of the invention may be used in a similar manner to perform audio monitoring and or audio and video monitoring. For example, data obtained at the microphone 14 of one or more smart sensors 10 a-n may be relayed to the user device 110 a via the external network 106 and output at the user device 110 a, e.g., in a manner similar to that described with respect to the video data.

FIG. 6 shows a block diagram of a system in accordance with aspects of the invention. FIG. 6 illustrates an aspect of the invention in which a smart sensor from a first system may be moved and operatively connected to a second system. In this manner, implementations of the invention provide a portable ‘on-the-go’ smart sensor that can be taken with a user and used alone or in other systems.

FIG. 6 shows a building 600 in which plural smart sensors 10 x, 10 y, 10 z are arranged in rooms 602 x, 602 y, 602 z. The building comprises a gateway 604 that provides a local network 608, e.g., in a manner similar to the gateway 104 of FIG. 4 . The smart sensors 10 x-z are connected in a mesh network 615, e.g. in a manner similar to that described with respect to FIG. 4 .

In the exemplary scenario depicted in FIG. 6 , userA has taken smart sensor 10 a away from local network 108 at building 100 and transported the smart sensor 10 a (e.g., carried it) and user device 110 a into the range of local network 608 associated with building 600. The smart sensor 10 a can operate on battery power from its battery 36 while it is in building 600, or may be plugged into an electrical outlet at building 600.

In the exemplary scenario depicted in FIG. 6 , the mesh network 615 defined by smart sensors 10 x-z represents a second mesh network that userA has permission to join. For example, the administrator of the mesh network 615 defined by smart sensors 10 x-z may permit smart sensor 10 a to connect to the mesh network 615. For example, the mesh network 115 of FIG. 4 may be that of userA's home, and the mesh network 615 of FIG. 6 may be that of a friend's house or a workplace.

In accordance with aspects of the invention, an individual smart sensor is configured to provide functionality when it connected to a second mesh network in the same manner that the smart sensor provides functionality when it connected to a first mesh network. For example, after the smart sensor 10 a connected to the mesh network 615 via the local network 608, userA may utilize the smart sensor 10 a to perform functions described with respect to FIG. 4 . For example, userA may utter a voice command to any of the smart sensors 10 a, 10 x, 10 y, 10 z to make a telephone call, and the receiving smart sensor will access userA's user device 110 a and initiate a call in a manner similar to that described with respect to FIG. 4 . It is noted that userA need not be in the same room as smart sensor 10 a and/or user device 110 a. Instead, userA may speak a voice command to smart sensor 10 z, and this receiving smart sensor 10 z interacts with smart sensor 10 a and/or user device 110 a to provide an output based on userA's input.

Still referring to FIG. 6 , as another example userA may utter a voice command to play music, and the system of smart sensors 10 a, 10 x, 10 y, 10 z will play music on a specified one or more of the smart sensors in a manner similar to that described with respect to FIG. 4 . The cognitive computing system 130 may also be leveraged in FIG. 6 in a similar manner to that described with respect to FIG. 4 in providing cognitive analysis that is used in generating an output at one of the smart sensors 10 a, 10 x, 10 y, 10 z in response to a voice input from userA.

The environment depicted in FIG. 6 is particularly useful in an exemplary use case comprising a hospital setting. For example, the building 600 may be a hospital and each of the rooms 602 x-z may be a patient room or an examination room that is outfitted with a respective smart sensor. In this example, userA may be a healthcare provider such as a doctor, nurse, etc. After initially registering the smart sensor 10 a with the mesh network 615, the mesh network 615 and smart sensor 10 a may be configured to cause the smart sensor 10 a to automatically connect to the mesh network 615 based on the smart sensor 10 a coming within range of the local network 608. In this example, the healthcare provider (e.g., userA) brings their own smart sensor 10 a and user device 110 a into the range of the local network 608, e.g., as they arrive for work. Once the smart sensor 10 a is connected to the mesh network 615, the healthcare provider (e.g., userA) may leave their own smart sensor 10 a and user device 110 a in a first room 602 x (e.g., their office) and utilize the functionality of the system while visiting patients in other rooms (e.g., rooms 602 y, 602 z). For example, the healthcare provider (e.g., userA) may make a telephone call or ask a question (for question and answer response) by voice interaction with any of the smart sensors 10 y, 10 z in the rooms 602 y, 602 z.

Additionally, the healthcare provider (e.g., userA) may carry their user device 110 a and use it to monitor data of smart appliances in other rooms via the smart devices 10 x-a of the mesh network 615. For example, mesh network 615 may interface with a heart monitor A1 connected to a patient in room 602 y, and the app 122 of the user device 110 a may be configured to permit the healthcare provider (e.g., userA) to visually view real-time data obtained from the heart monitor A1 even when the healthcare provider (e.g., userA) and the user device 110 a are in a different room.

FIG. 7 shows a flowchart of a method in accordance with aspects of the invention. Steps of the method of FIG. 7 may be performed in the system illustrated in any of FIGS. 4-6 and are described with reference to elements and steps described with respect to FIGS. 1-6 .

At step 701, an app is installed on each user device that is to be used with the system. In embodiments, as described with respect to FIG. 4 , an app 122 may be installed on each user device 110 a-c. In accordance with aspects of the invention, the app 122 is configured to provide different types of accounts to different users. For example, the app 122 is configured to permit at least one user to register as an administrator (also called master control) and to permit at least one other user to register as a normal user. In embodiments, the administrator is provided with all the functionality of a normal user, and in addition is provided with administrative controls and privileges. For example, the administrator can control, via the app 122, how many user devices (e.g., user devices 110 a-c) and how many users (e.g., userA, userB, userC) can register with the system. For example, the administrator can use the app 122 to invite a user to register with the system, to accept a request from a user to register with the system, to revoke a user's registration with the system, and to control what user data the system can access for each respective registered user.

At step 702, the app on the user device initializes the user device with the one or more smart sensors of the system. For example, the app 122 may be configured to cause the user device (e.g., user device 110 a) to establish two-way communication with at least one smart sensor (e.g., smart sensor 10 a) via wireless communication (e.g., via the local network 108). The app 122 may detect plural mesh networks, in which case step 702 may include displaying all detected mesh networks to the user via the user device and receiving input from the user of a selection of which of the mesh network to join. Step 702 may also include syncing each smart sensor in the selected mesh network to the user device, and syncing all of the smart sensor in the selected mesh network to one another (e.g., via peer interaction modules 42).

At step 703, the user of the user device registers with the mesh network. Step 703 may include the user entering credentials (e.g., password) via the app 122 to join the mesh network. The credentials may be provided to the user based on the administrator granting permission for this user to join the mesh network.

In embodiments, step 703 also includes the user providing voice samples to set up the smart speech recognition as described herein. For example, the app 122 may cause the user device to prompt the user to provide voice samples, e.g., by asking the user questions or instructing the user to state certain words, phrases, sentences, etc. The voice samples are received via the microphone 14 of one or more smart sensors in the mesh network and are stored for later use in smart speech recognition as described herein. The voice samples may be stored at any suitable location.

At step 704 the user interacts with one or more of the smart sensors in the mesh network. For example, the user may utter a voice command that is received by one or more of the smart sensors in the mesh network. In embodiments, and as described herein with respect to FIGS. 4-6 , the system uses smart speech recognition to determine which user (of plural registered users) uttered the voice command, processes the voice command into an instruction, and carries out the instruction. In embodiments, the carrying out of the instruction may be based on user data that the system accesses based on determining which user uttered the voice command.

FIG. 8 shows a flowchart of a method in accordance with aspects of the invention. Steps of the method of FIG. 8 may be performed in the system illustrated in any of FIGS. 4-6 and are described with reference to elements and steps described with respect to FIGS. 1-6 .

At step 801, a smart system is set up. Step 801 may include plugging plural smart sensors 10 into different electrical outlets, and using the app 122 to define a mesh network containing the plural smart sensors 10, e.g., as described with respect to FIG. 4 . Step 801 may also include registering one or more users and user devices with the mesh network, e.g., by the users performing the steps 701, 702, and 703. In some embodiments, step 801 may include a user connecting their smart sensor to an already existing mesh network, e.g., as described with respect to FIG. 6 .

At step 802, a voice command is received by the smart system. In embodiments, and as described with respect to FIGS. 1-6 , a user may utter (e.g., speak) a voice command that is detected by the microphone 14 of one or more smart sensors 10 in the mesh network of the smart system.

At step 803, the smart system resolves the voice command of step 802 into an instruction. In embodiments, and as described with respect to FIGS. 1-6 , the voice control module 40 of the receiving smart sensor determines an action to perform based on the voice command that was received at step 802. Step 803 may be performed using techniques including but not limited to: converting speech to text, natural language processing of the text, and applying predefined rules based on the text and/or the natural language processing of the text.

At step 804, the smart systems determines a user that provided the voice command of step 802. In embodiments, and as described with respect to FIGS. 1-6 , the system uses smart speech recognition to determine which particular user of plural registered users provided the voice command. The smart speech recognition may be performed locally at the smart sensor (e.g., by the voice control module 40), remotely at a cloud-based server (e.g., cognitive computing system 130), or some combination of both. In both implementations, the smart systems compares the received audio data (e.g., the voice command received at step 802) to stored data associated with each registered user (e.g., voice samples provided during registration, e.g., at step 703), and uses voice recognition techniques to determine which of the registered users provided the voice command.

At step 805, the smart system access user data associated with the determined user from step 804. In embodiments, and as described with respect to FIGS. 1-6 , the system accesses a user device associated with the determined user. For example, the smart sensor may communicate with the user device via the mesh network 115 and/or the local network 108, and may access user data that is stored in the user device. The user data may include, for example and without limitation, at least one of a contact list, stored music, credentials for a music streaming service, user preferences received via the app 122 (e.g., voice, vocabulary, content controls), and credentials for a question and answer system. Other user data may also be used.

At step 806, the system carries out the instruction (from step 803) based on the user data (from step 805). In embodiments, and as described with respect to FIGS. 1-6 , the system generates an output and/or performs a function that is based on both the instruction and the user data. For example, in the event the voice command was to make a telephone call, then step 806 may include the smart sensor causing the user device to initiate a telephone call based on accessing a contact list store on the user device, e.g., as described with respect to FIG. 4 . In another example, in the event the voice command was to play music, then step 806 may include the smart sensor playing music based on a music library (or streaming service credentials) stored on the user device, e.g., as described with respect to FIG. 4 . In another example, in the event the voice command was to turn on the television, then step 806 may include the smart sensor sending an instruction to a television based on preference data of the user, e.g., as described with respect to FIG. 4 .

In accordance with aspects of the invention, step 806 may include performing a cognitive analysis and carrying out the instruction at least one part based on the cognitive analysis. The cognitive analysis may be performed locally at the smart sensor (e.g., by the cognitive module 48), remotely at a cloud-based server (e.g., cognitive computing system 130), or some combination of both. The cognitive analysis may include, for example, at least one of tone analysis, speech rate analysis, and speech volume analysis based on a voice command received at the speaker of the smart sensor.
